BMW M3 E30 DTM 1/12 Conversion/Scratchbuild
Hi,here are the first pics from my latest scratchbuild/conversion project.
I want to create a BMW M3 touring car.The car won lots of champions ships all over the world. Here are the first steps to make the mold of it. Lots of changes to the master. On the inside i made lots of sanding. The base plate for the body. Looks fine. The wooden frame to hold the silicon. Put together and hold with stripes in place. The master was brushed with a thin coat of silicone to prevent it from airbubbles. Outer frame sits into the place.Ready for casting. The hole for fill in. Mold is filled with 3,5kg silicone. After one night its ready for molding.The inside looks fine. The block for the inner core. Ready for casting with quick setting-resin. Casted and ready for some sanding. The frame was rebuilded for molding the silicone. Some cleaning is necessary,but the molds looks good. And here are the result. The first castings looks very good.Only some smaller bubbles at the front.But i try to prevent them with a different filling of the mold. I do my best. Next step are the wheels/rims. Thanks Christian |

Chris, nice project!
Try to cast with pressure chamber *– it will remove air bubbles from the resin. |

Re: BMW M3 E30 DTM 1/12 Conversion/Scratchbuild
Thanks for the hint with the pressure chamber.But how big should this be for my molds?I dont got enough space for building,so where i should put this chamber?
Next step are the two different mirros. Thats the late version.The rear wing was also different,but can be changed from hand i think. Now the first version. Rims with nuts and the dashboard. 4 different versions of the steering wheel.The one i choose are the one i designed from two different ones. regards Christian |

Re: BMW M3 E30 DTM 1/12 Conversion/Scratchbuild
Now the printed parts arrived from shapeways.
Many thanks to Torsten who made the design for me. The rollcage fits perfect into the body.Too good. When the body and the floor is assembled its too tight.Need to cut it and glue it together.But first when the chassis is done. Created the inner structure and sanded it a bit.Now the structure is done and need to fill the holes all around for casting. The "Fina" wheels are also printed.But i miss the outer rim ring.So i made one from an old Tamiya rim and sanded it up to 2mm. Some glue on it and the rim was ready. More to come soon. regards Christian |

Re: BMW M3 E30 DTM 1/12 Conversion/Scratchbuild
Final version of the rims are ready for casting.
I changed the width of the tires a bit.Now its all fine. The next step is finish the chassis master for making the mold. Thats the final part of the model making. regards Christian |

Re: BMW M3 E30 DTM 1/12 Conversion/Scratchbuild
The chassis master is created and i just casted it into resin.
That was the last mold i need.Next are the rollcage.I got a printed one here,but needs some refitting. regards Christian |

Re: BMW M3 E30 DTM 1/12 Conversion/Scratchbuild
Some parts are primed to test it.
The chassis with rear trunk cover is done. Some fitting test with the BBS style rims. Overall i think its ok so.Some thinning in the wheel arches can be made maybe. But the look is ok,i think. Tomorrow i will test the Fina wheels,but they should fit the same. Than i cut the roll cage to fit it into the car. Thats the last step,i hope. regards Christian |

Re: BMW M3 E30 DTM 1/12 Conversion/Scratchbuild
In the meantime i found some time to create the cage.
It looks fine for me.Only the "X" behind the driver seat is a bit out of shape.But dosent matters to me.It cant be seen once the body is on. Now i hope the my CAD constructor could create a new cage out of my data. regards Christian |

Re: BMW M3 E30 DTM 1/12 Conversion/Scratchbuild
Today i put the M3 on the other wheels.Looks fine.
Dashboard was installed and also the steering wheel.Works. The rear wing was put in place with two pins and the exhaust was created. For the exhaust i used a piece of "Ureol" and sanded it in shape. Than i took two pipes plastic and made the angle with some heat. On top i put two "Aderendhülsen" (some electrical stuff in different sizes) as the exhaust pipes. Simple sanded it with a different angle and thats it. Now i have to cast the exhaust in resin and put two "Aderendhülsen" into the kit. regards Christian |
